Title: Improvements in the manufacture of base exchange material
IPC: C01B33/46
Filed: 1938-07-07
Abstract: 519,872. Softening water. NIELSEN, H., and AKTIESELSKABET FAERO-KUL. July 7, 1938, No. 20183. Drawings to Specification. [Class 46] [Also in Group III] A base-exchange material is obtained from non-plastic clay, such as that found in the coal measures of the Faroe Islands, by subjecting the raw material to a regulated heat-drying treatment, granulating the dried material by slaking with water, and removing the coarser material and fines. For drying the temperature should not exceed 125‹ C., and this step is carried out in such manner that the same percentage of water is removed from the coarser as from the finer material. For this purpose a rotary drier having circumferential sieves of different mesh, so that the finer material has a shorter passage through the drier, may be used. The slaking is preferably performed by counter-current in a rotary container. Vibrating sieves immersed in water liquid are used to separate successively the coarser material and fines from the slaked material. The material may be finally dried by means of a centrifuge.

Filed: 1972-05-03
Abstract: 1429311 Moulding apertured articles EMI Ltd 19 April 1973 [3 May 1972] 20513/72 Heading B5A In a method of moulding an apertured article, e.g. a gramophone record, two co-operating hole-forming members 8, 9 are pressed together (Fig. 2) at a position within the thickness of the article, one of the members being subsequently moved beyond that position to sever any thin webs formed between them. As shown the member 8 forms the tip of an injection nozzle 5 and holds one of two labels 4. In its forward position the nozzle 5 engages a conical seat 7 in a fixed mould part 1. The member 9 has an enlarged head 11 slidable in a bore 12 in a movable mould part 2. A second label 4 is held by the member 9. The mould parts are not completely closed until after the moulding material has been injected. As the mould closes, the members 8, 9 are brought into contact to form the central hole in the article. The force P 1  applied to the nozzle 5 is now reduced to a value P 3  (preferably zero) which is lower than the force P 2  applied to the member 9. The nozzle s thus moved by the member 9 until the head 11 engages a shoulder 12A, thus forming gaps 16, 17 (Fig. 3). On separating the mould parts 1, 2 air may be introduced into the gap 17 to ensure that the moulded article remains attached to the movable mould part 2 from which it is subsesequently removed. In a modification the article is made by a compression moulding method using a cake of mouldable material, the nozzle 5 being replaced by a solid member. Reference has been directed by the Comptroller to Specification 1,30,1095.

IPC: A61K38/01
Filed: 1958-06-27
Abstract: Non-gelatinous protein hydrolysate suitable for parenteral use is lyophilized in aqueous solution containing, in addition to the protein hydrolysate, a gelatin hydrolysate having a gel point of 15 to 20 DEG C. in 26 to 35% aqueous solution and being present in a ratio of 1 to 2 parts of gelatin hydrolysate to 9 parts of the non-gelatinous protein hydrolysate; it is stated that the foaming problem normally encountered does not become apparent to any appreciable extent when the partially hydrolysed gelatin is included. The gelatin hydrolysate may be made by hydrolysing an aqueous solution of gelatin for three hours at approximately 250 DEG F. and 15 lbs. per sq. inch pressure.  According to an example, to 1,470 ml. of 23% casein hydrolysate in which 69% of the total nitrogen was in the form of a -amino nitrogen, there was added 188 ml. of hydrolysed gelatin prepared as described above and containing 32% solids. Vitamins &c., dextrose and sodium ethyl mercurithiosalicylate were added and the total volume of the solution was brought up to 3,08 litres with warm pyrogenfree distilled water.  After filtering, 77 ml. portions of the solution filled into 250 ml. brown-glass bottles were frozen at -60 DEG F. and then placed in a lyophiliser, the pressure being decreased to 50-150 microms.  The bottles were finally removed from the lyophiliser and aseptically stoppered.  The product, which contained less than 5% of moisture, reconstituted readily with pyrogen-free distilled water.  Other examples are concerned with lyophilising bovine plasma and fibrin hydrolysates.
